消息通知__操作指南_批量计算-阿里云

消息通知

批量计算服务（BatchCompute）使用MNS提供的主题模式来实现消息通知。用户负责主题（Topic）的创建、管理和订阅，并在使用BatchCompute创建集群或提交作业时指定主题相关的配置。BatchCompute依据配置向指定用户主题推送消息。用户可在MNS控制台配置URL、队列、邮件和短信四种方式获取消息通知。

1. 前期准备

(1) 开通消息服务

(2) 创建MNS主题

(3) 创建MNS主题订阅

(4) 授权BatchCompute推送消息

请登录控制台上进行一键授权。如果没有授权过，控制台导航条下面会出现这个提示:tu如果已经授权过请忽略本条。

2. 计费相关

消息通知产生的费用统一由消息服务结算，批量计算不再额外收取。

3. 创建BatchCompute集群

使用SDK或控制台创建集群（cluster）时，可以配置如下类型消息事件（AutoCluster类型作业不支持消息通知）。

  1. {
  2.     "Notification": {
  3.         "Topic": {
  4.             "Name": "test-topic",
  5.             "Endpoint": "https://[UserId].mns.[Region].aliyuncs.com/", 
  6.             "Categories": [
  7.                 "OnClusterDeleted",
  8.                 "OnInstanceCreated",
  9.                 "OnInstanceActive"
  10.             ]
  11.         }
  12.     }
  13. }
字段 说明
Name MNS主题名称
Endpoint MNS私网Endpoint，如何获取Endpoint。

4. 提交BatchCompute作业

使用SDK或控制台创建作业（job）时，可以配置如下类型消息事件。

  1. {
  2.     "Notification": {
  3.         "Topic": {
  4.             "Name": "test-topic",
  5.             "Endpoint": "https://[UserId].mns.[Region].aliyuncs.com/",
  6.             "Categories": [
  7.                 "OnJobWaiting",
  8.                 "OnJobRunning",
  9.                 "OnJobStopped",
  10.                 "OnJobFinished",
  11.                 "OnJobFailed",
  12.                 "OnTaskWaiting",
  13.                 "OnTaskRunning",
  14.                 "OnTaskStopped",
  15.                 "OnTaskFinished",
  16.                 "OnTaskFailed",
  17.                 "OnInstanceWaiting",
  18.                 "OnInstanceRunning",
  19.                 "OnInstanceStopped",
  20.                 "OnInstanceFinished",
  21.                 "OnInstanceFailed",
  22.                 "OnPriorityChange"
  23.             ]
  24.         }
  25.     }
  26. }
字段 说明
Name MNS主题名称
Endpoint MNS私网Endpoint，如何获取Endpoint。

5. 事件消息格式

消息格式目前支持json string。
